Adaptive overcurrent protection against ferroresonance

IET Generation, Transmission & Distribution, 2018
Catastrophic equipment failures continue to occur today due to ferroresonance even though this phenomenon has been extensively studied over the past 90 years. Ferroresonance may also cause mal operation of some protective devices like overcurrent protection.

Current limiting device for overcurrent protection

, 1983
A current limiting device for use with a circuit breaker in an electric power system utilizes mutual inductance variation between movable windings to limit current to safe levels. In the device, first and second coil windings are electrically connected for current flow therethrough and magnetically linked for mutual inductive coupling.
